doi:10.15541/jim20160683

Abstract

Abstract:

Fe₃O₄ magnetic core particles was prepared by hydrothermal method with a particle size of 150-300 nm, which showed good dispersibility. After amination of Fe₃O₄ particles by APTES, combined with in situ reduction of H₂PtCl₆ with NaBH₄, we obtained Fe₃O₄@Pt with core-shell structure, and used it as a DMFC anode catalyst. The composition, morphology and structure of Fe₃O₄@Pt were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and energy-dispersive X-ray spectroscopy (EDS). The electrocatalytic activities of Fe₃O₄@Pt were also investigated by cyclic voltammetry (CV). As a result, the surface of Fe₃O₄@Pt particles mainly composed of Pt. The particle size of Fe₃O₄@Pt particles is between 200 nm and 300 nm. Atomic ratio between Fe and Pt is about 3:1. The prepared Fe₃O₄@Pt particles have a good stability. After 100 cycles, the cycle peak current density of the 101th’ cyclic voltammetry curve of glassy carbon electrode modified by Fe₃O₄@Pt in fresh 0.5 mol/L H₂SO₄+1 mol/L CH₃OH aqueous solutions is 94.51% of the first cyclic voltammetry curve. The peak current density of pure Pt is only 90.73% compared with that of Fe₃O₄@Pt. The charge transfer between Fe₃O₄ and Pt improves the catalytic activity Fe₃O₄@Pt. As a result, this work demonstrates the potential of Fe₃O₄@Pt catalyst to replace Pt as the anode of DMFC in the future.
